LocalPDF is a privacy-first PDF toolkit designed for users who value security, speed, and simplicity. Unlike traditional online PDF tools that upload your documents to remote servers, LocalPDF processes everything locally in your browser.
Our Mission
We believe that working with PDFs shouldn't require sacrificing your privacy. Every day, millions of people upload sensitive documents—contracts, invoices, medical records, tax forms—to cloud-based PDF services without knowing where their files go or who has access to them.
LocalPDF changes that.
By leveraging modern web technologies (WebAssembly, PDF.js, pdf-lib), we've built a complete PDF toolkit that runs entirely in your browser. Your files never leave your device. No uploads, no tracking, no data collection.
Why We Built This
Privacy Matters
Your documents contain sensitive information. They shouldn't be uploaded to servers you don't control, scanned by algorithms you don't understand, or stored in databases you can't delete.
Speed Wins
Uploading large PDFs to servers is slow. Processing in your browser is instant—no network delays, no queues, no waiting. Just pure, native performance.
Simplicity First
No accounts, no subscriptions, no paywalls. Just open a tool, drag your file, and get results. The way software should work.
How It Works
LocalPDF uses client-side JavaScript libraries to manipulate PDFs directly in your browser:
- pdf-lib — For merging, splitting, compressing, and protecting PDFs
- PDF.js — Mozilla's open-source PDF renderer for previews and OCR
- Tesseract.js — OCR engine that extracts text from scanned documents
- React 19 — Modern UI framework for smooth interactions
When you upload a file, it stays in your browser's memory. Processing happens using WebAssembly and JavaScript—no network requests, no server communication. When you download the result, the file is generated locally and saved to your device.
Open Source & Transparent
LocalPDF is built on open-source technologies. We believe in transparency and community-driven development. Our codebase uses battle-tested libraries trusted by millions of developers worldwide.
Our Principles
- Privacy by Design: Your files never leave your device. Period.
- No Tracking: No cookies, no analytics, no user profiling.
- No Accounts: Use all tools without registration or email.
- Free & Fair: No artificial limits, no watermarks, no upsells.
- Performance: Instant processing with no upload delays.
GDPR Compliance
LocalPDF is inherently GDPR-compliant because we don't process, store, or transfer personal data:
Zero Data Collection
We don't collect, process, or store any personal data. No cookies, no tracking scripts, no analytics. Your files are processed entirely in your browser's memory and deleted when you close the tab.
No Data Controllers
Under GDPR, a "data controller" determines the purposes and means of processing personal data. Since LocalPDF never receives your data, we're not a data controller—there's nothing to control.
Right to Erasure? Automatic.
GDPR grants you the "right to be forgotten." With LocalPDF, your data is automatically erased from browser memory the moment you close the tab. No manual deletion requests needed.
